I go to install the drivers and they compile fine and it installs then when I go to run sax2 I get a message saying it can't start X and to check my log at /var/log/Sax.log and toward the bottom of that log it shows

NVIDIA: could not open the device file /dev/nvidia0 (input/output error)

I've googled this for the past 4 hours and tried chmodding the nvidia* files in /dev and everything anyone else has suggested I have also tried 3 different drivers. Last time this happened when I restarted to try to boot my system it just hung and I had to reinstall! so I'm not going to restart i'm just leaving it as is so I have shell access. Please HELP. Thank you very much for your time.

Ok I got past that i had to update my bios. I have a m2n32-sli deluxe asus motherboard. so I got the driver installed ran sax2 -r. then was looking good then I restarted and went to boot normally now i get lots of irq information then toward the bottom of boot it says Code: 83 3f 00 7e f9 e9 6d fe ff ff e8 c7 d5 ff ff e8 7d fe ff ff
console shuts up ...
<0> Kernel Panic - not syncing: Aiee, killing interrupt handler!

and it's frozen... is there a way I can boot to konsole and undo the driver install? I'm lost I would appreciate some guidance. TIA
